Now we've got a polyethylene glycol sample with high polarity and about 4000 MW. The sample is liquid which looks like oil with about 27% water. Present we have not GFC column but some GPC columns and the task is very urgent. So I wonder if we could use GPC column to analyze such hydrophilic sample with high content of water? Will such kinds of sample harm the column?
And since I guess we can not use tetrahydrofuran to elute the hydrophilic sample, shall we use some high polarity solvents such as DMF? Or which kind of solvent is suitable?
Thank you if you can help me!
